Cryptography Research to Provide Patented Security Technology to Raytheon

SAN FRANCISCO, Calif. — February 9, 2005 — Cryptography Research, Inc., a worldwide leader in security systems, today announced that it has licensed its Differential Power Analysis (DPA) countermeasure technologies to Raytheon Company (NYSE: RTN). In addition, Raytheon also purchased a tool suite and training for its personnel to establish an internal group focused on DPA countermeasures.

"DPA can be used to break implementations of almost any symmetric or asymmetric cryptography algorithm, including proprietary and heavily modified industry standard algorithms. The widespread use of strong cryptography in both software and hardware has given DPA attacks and countermeasures an increased importance," said Paul Kocher, president and chief scientist of CRI.

"We are pleased to be working with Raytheon Company, and that they selected CRI for its leading-edge countermeasure technologies," said Kit Rodgers, vice president of licensing.
